Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Angelo Basic GIS Coverages
    (2024-06-13) Bode, Collin; collin@berkeley.edu; Bode, Collin; National Center for Earth-Surface Dynamics (NCED)
    Projection: UTM, zone 10, datum NAD83. GIS file format: ESRI Shapefile for vector, ESRI arcinfo binary GRID format for raster. Data Sources: National Center for Airborne Laser Mapping (NCALM, http://ncalm.berkeley.edu): Lidar DEM of the South Fork Eel watershed at Angelo reserve was created by NCALM. This data is new and still is being post processed. The dem is extremely high quality (1m resolution). California Spatial Information Library (CASIL, http://gis.ca.gov): public and federal datasets, including USGS drg, doqq, and blue-line datasets. Naming Conventions: This is not strictly followed. Files start with their spatial scale and end with their projection. Maps will often end with their DPI resolution. Eel: entire eel watershed Sfk: South Fork Eel Nfk: North Fork Eel Angelo: Angelo Reserve

    Eel River 10m Digital Elevation Models (DEM) [2007]
    (2024-06-06) Bode, Collin; collin@berkeley.edu; Bode, Collin; National Center for Earth-Surface Dynamics (NCED)
    Eel Watershed digital elevation models (DEM). This DVD contains DEMs of the entire Eel River watershed. The Eel River is located mostly in Mendocino County on the coast of California. The source data for these DEMs comes from NED, USGS. Source data was 10x10 meter resolution in ESRI ArcInfo grid format and in geographic (lat/long) projection with NAD83 datum. It was downloaded from: http://seamless.usgs.gov/ The National Center for Airborne Laser Mapping (NCALM) processed the source grids as follows: 1. merged the tiles into one grid. 2. reprojected from geographic to UTM, zone 10, nad83 projection using bilinear interpolation. 3. Ran a series of analyses on the dataset to produce the following DEMS eel10mdem: Basic grid of elevation, 10m resolution eel10mdemacc: Flow accumulation. Grid shows how many other grids flow into each square. Used for watershed delineation and for channel creation. eel10mdemdir: Azimuth. Shows direction from north a grid cell is facing. Only 8 directions used, moving clockwise. eel10mdemfil: Sinkfill.To get the flow accumulation, you must fill holes and pockets in the elevation model. This grid is essential a step in the processing. eel10mdemshd: Hillshade. Models realistic afternoon sun hitting the elevation model. Excellent for visualization. Any questions should be directed to NCALM. http://calm.geo.berkeley.edu/ncalm Dino Belugi can answer processing questions. dino@eps.berkeley.edu Collin Bode can answer general questions about the dataset. collin@berkeley.edu

    UNDER CURATORIAL REVIEW: Eel River Flipchart [2007]
    (2024-06-12) Bode, Collin; Power, Mary; Power; collin@berkeley.edu; Bode, Collin; National Center for Earth-Surface Dynamics (NCED)
    This is a 34 page flipchart of the Angelo Reserve. Each page is an 8.5x11 map of a river segment. The maps show the location of the highest accumulated streamflow (using DEM) as the river, even though the channel is wider, and use the vegetative canopy DEM colored by vegetation height. Note the decision to use canopy instead of the traditional bare-earth is to provide visual references while out in the field. Bare-earth provides little help when maps are zoomed in this close. Laminated versions will be availible at the ACCR Science Center to be used during field sampling. Sampling sites can be drawn directly on the maps with a sharpie then removed later using alcohol. Marked up maps are to be either copied using the xerox machine, or scanned. Scanned versions can be sent to Collin Bode to convert the points into a GIS coverage.
